' ,2 cl ans, (01, 103234) It is also an important object of the invention 7 to provide a novel construction of air valve for use with the pump, the latter including a valve for ready release of air from the system, thus permitting quick refilling of a submerged water cylinder of the apparatus, for the next pumping operation.

It is a still further object of the invention to provide a pump which is of extremely simple construction, of few parts, liable in a minimum degree to derangement, and in which the manual efiort to efiect starting and stopping of the pump is greatly reduced.

Additio'nal objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a vertical section through a well having my pump installed therein.

Figure 2 is a vertical section through the air valve of the device.

Figure 3 is an elevation and top plan view of the lower housing of the valve.

Figure 4 is an elevation and top plan view of the upper housing of the valve.

Figure 5 is an elevation and top plan view of the air regulating valve.

Attention is first invited to Figure 1 of the drawing, wherein there is shown a well in which there is disposed a cylinder ll submerged The discharge pipe I 4 has a check valve permitting passage of water through a water discharge end I6 and operative to maintain a head of water above the check valve l5.

An air line I! is also connected with the upper end of the cylinder and includes an air inlet .stantially as shown in Figure 1.

valve 8, as will now be described, attention being invited particularly to Figure 2. The valve includes a lower hexagon-shaped housing IS, in-' teriorly threaded as at 20, concentric with a bore 2| formed in a reduced nipple 22. The nipple 22 is exteriorly threaded as at 23 and receives thereon an upper housing 24, the upper end 25 being of reduced diameter so as to accommodate a chuck of an air hose, as will be described. The bore 26 of the housing is concentric with the bore 2| when the housings are in assembled relation.

The housing 24 is also formed with a cylindrical portion 21 inwardly of the threads of the housing so that when the housings are connected, a valve chamber is provided loosely housing a disk valve 28. The valve 28 is formed with a central opening 29 and a plurality of openings 30 arranged concentric of the disk. It will be'noted that during admission of air, the disk will lie immediately above and upon the nipple 22 so that the openings 30 are closed to passage of air, the air required for elevating water passing through the central opening 29. The central opening 29 is of a diameter less than the openings 30 so as to restrict the ingoing air the proper amount during the pumping operation to insure a steady and not too violent flow of water from the dis charge I6. The larger openings 30 permit discharge of air after pumping operation, as will be explained.

As has been stated, the present pump is particularly useful in service stations located in outlying districts where the water required is obtained from a well by means of a hand pump or windlass and bucket, which may be eliminated and in their stead, the cylinder ll and'connected water and air lines l6 and I! are installed in the well, sub- The air and water lines are preferably entrenched beneath the surface of the ground, for protective reasons,

but are directed upwardly above the surface, the

water pipe terminating in the discharge l6 and the air line I! having the valve l8 secured thereto.

To operate the pump, the air line of a conventional compressor is employed, the chuck of the line being manually applied to the reduced end 25 of the valve. Air will pass into the valve l8 and through the central opening 29 and into the air line 11, thus building up a pressure in the cylinder ll. Water will have previously entered the cylinder by way of the foot valve l3. As the pressure builds up in the cylinder, water will be forced upwardly through the check valve l5 and outwardly through the discharge I 6 where it may be received in a suitable receptacle. To stop the pumping operation, the air line chuck is simply removed from the valve l8, permitting outward flow of air from the cylinder I I. The pressure of outgoing airwill elevate the disk valve 28, the

openings 29 and 30 of the disk valve permitting ready escape of air to the atmosphere and insuring a quick refilling of the cylinder with water. It will be seen that the check valve l5 will maintain a head of water thereabove so that the next pumping operation can be started without undue delay.

While I have shown and described a, preferred form of the device, this is by way of illustration only, and I consider as my own all such modifications in construction as fairly fall within the scope of the appended claims.

I claim:

. constructed to maintain a head of water above 1. Means for elevating a liduid from a well com-,

prising a cylinder within the well submerged beneath the water level, said cylinder including a foot valve, a Water discharge line connected to said cylinder and having a check valve, an air said check valve, an air line connected to said cylinder at an upper part thereof, said air line having a fitting at the terminal end thereof, said fitting having an axial port, a disk valve loosely disposed within the chamber, said disk valve having an axial opening and a plurality of openings concentricwith said disk normally closed by the base of said chamber, and an air chuck and line detachably connected to said fitting.
